To all where may concern:

Be it known that 1, Dan; B. Manama, of "Co 'oleshill, in the county cu Soheharie and State of New Yorh,have invent-e5 certain new and useful improvements in Fertilizer Distributers; and 1 do hereby declare the following to he a ful e; .r, and exact description of'the same, reference had to the accompanying drawings, forcing; a part this s iecineation and to the relerencee merals marked thereon My present in; ention. ments fertilizer diet. 2 for its object to provi vices for oper Vance the mat the heaters, the

Such a machine in the present forms of the invention comprises asuitable body 1 having the vertical sides 2, the load neirg supported on the forward and rear Wheels 3 and 4, the latter belng util zed for driving the vario us devices which operate during the spreading. Between the sldes of rier 5, that hown in the present form being an enoless carrier made up of a plurality or sections or s s 6 extending transversely h roes ood between the sides thereof,

sfats 'seing hinged together to per- 1 to pess over the sprocket Wheels i through the section 111% 9, notch 13 being coi'res ending with le men; er to accointeeth. The vertical he angle member has its oppoe ends ended beyond the end of the ,"lOlllflllizll flange U to form hinge members, indicate-ism l4 15, these hinge incinoers being perforated to receive the rivets 16 which serve to join the adjacent angle menilz-ers of the carrier.

he shaft 17 to which the sprockets 7 are lined has a Worm wheel 18 loosely mounted thereon, preferably at the outer side of the. body, and this 'woi'ni Wheel has a clutch face 19 thereon adapted to cooperate with the corresponding clutch member 20 which is slideblc axially oi the shaft, but is caused to turn therewith by means of the spline 21, the Worm Wheel 18 being connected and disconnected in relation to .the shaft by shifting clutch member 2?} leg suitable means such as a lever 2 3 is mounted a movable platform 011 The feed devices shown in Figs. 2 and 3 embody a shaft 23 journaled in bearings 24 and 25 secured to a suitable part of the body, the said shaft having a worm 26 fixed thereon and arranged to coperate with the worm wheel 18 to operate it, and this shaft also carries apair of oppositely-arranged pinions 27 and 28. These pinions'. are loosely mounted on the shaft andv are adapted to be connected therewith by means of the ratchets 29 and 30 which are suitably inter osed between their respective pinions an the collars 31 and 32, the latter being fixed to the shaft, the ratchetdevices being arranged to form an operative connection between their respective pinions and the shaft when the pinions are operated in one direction, to permit the pinions to operate freely in the reverse direction. Cooperating with both pinions is a gear or segment 33 mounted to rotate onan axis 34, the said axis being arranged at a point intermediate between the pinions and preferably coincident with the apexes of their cones, so as this gear rotates in one direction, it will operate the pinion 27 in a proper direction to rotate the shaft 23, and when it is rotated in a reverse direction it will operate the pinion 23 to rotate the said shaft a second step, the inion in each case which is not operating the shaft being permitted to rotate backwardly by the ratchet connection between it and the shaft. This wheel or segment 33 is provided with the rocker arm 35 adapted to receive the slide 36, the latter having a catch 37 thereon adapted to cooperate with the spaced notches 38 on the rocker arm to rovide for adjusting the position of the slide ongitudinally of the rocker arm. To this slide is attached a link 39 arran ed to be reeiprocated by a crank 40, and this crank is connected in any suitable way with the driving wheels, a sprocket wheel 41 being provided in the present instance over which the chain 42 passes, the chain in turn being operated by the sprocket Wheel 43 driven from one of the driving wheels 4. As machine is caused to move over the ground the driving wheels 4 will be operated, and through the chain 42 rotary motion will be transmitted to the crank 46, the latter in turn imparting reciprocatory motion to the link 39. As this link is con nected to the slide 36, the latter is connected to the rocker arm 35, the reciprocatory motion of the link 39 will be utilized to produce a rocking movement of the gear 33, first in one direction and then in the reverse direction, and the rocking movement of this gear will be transmitted alternately through the pinions 27 and 28 to produce the rotation of the shaft 23 in the same direction. The worm 26 fixed to this shaft will transmit the motion thereof to the worm wheel 13, and through the clutch members 19 and 20 this motion will be transmitted to the shaft 17,

carrying the sprocket wheel 7, and asthese sprockets rotate, a rearward movement will be imparted to the platform or carrier 5, causing it to move the load of material contained by the body of the vehicle to be carried rearwardly and fed to the beater or spreading device. The relative rate of feed of material is governed by the movement of the carrier 5, and this may be regulated by setting the slide 36 at different positions on the rocker arm 35, the catch 37 serving to hold the slide and rocker arm' in adjusted relation.

In Fig. 4 a modified construction of the invention is shown, a frame 44 being attached to the side of the body for supporting the intersecti g shafts 45 and 46, the shaft 45 being provided with a bend 47 so as to clear the shaft 46. On the shaft 45 a sleeve 48 is loosely mounted, this sleeve carrying a worm 49 arranged to coperate with the worm wheel 18 on the shaft 17, a pinion 50 being also fixed to the sleeve 48. On the shaft 46 are loosely mounted a pair of oppositelyarranged bevel gears 51 and 52, the latter engaging the pinion 50 at opposite sides, and each of these bevel gears is provided with a ratchet 53 and 54 with which are arranged to coperate the pawls 55 and 56, each of these awls being carried by the rocker arm 57 1ournaled on the shaft 46, a slide 36 having a connecting link 39 being also provided as shown in connection with the form illustrated in Fig. 2. As the rocker arm 57 is operated by the link 39, the pawls 55 and 56 will operatively engage alternately with their respective ratchet wheels 53 and 54, and as the rocker arm moves in one direction, the bevel gear 51 will be rotated to operate the pinion 50, while the gear 54 runs loose, and vice versa,

the motion imparted to the pinion 50 causing the worm 49 to rotate the gear wheel 18, and in this Way an intermittent motion is imparted to the carrier 5.

- Fig. 6 illustrates another form of the invention embodying a shaft 57 journaled in the bearings 53 and 59 and having a pinion 60 and a worm 61 fixed thereto, the worm 61 being arranged to coliperate with the worm wheel 18, which is mounted on the shaft 17. Meshing with thepinion 60 is a gear 62 having a ratchet face with which the pawls 64 and 65 e06 )erate, and. these pawls are pivoted to a roefrer arm'66 which 1s pivoted to the body at 67, so that as this arm is rocked.

about its center, the pawls 64 and 65 will 0 aerate in opposite directions, each engaging alternately with the ratchet face on the gear 62 to rotate it in a given direction, the motion being transmitted from the gear through the pinion 60 in worm 61 to the worm wheel 18, and from the latter it is transmitted to the traveling carrier. The rocker arm in this construction maybe operated in a manner similar to that described in connection with the form shown in Figs. 2 and 4, that is, the arm 66 may be provided with the adjustable slide 36, which receives its motion from the reciprocatory link 39. The angle members which are applied to the ends of the slatsor sections of the carrier are so' fitted that the vertical flanges fit closely to the sides of the body, and at the inner sides of the body are provided the rows of supporting rollers 68, on which the horizontal flanges 9 on the angle members bear,

. and .in this way a substantiallycontinuous metallic bearingis provided for the movable )latform or carrier, the sprockets 7 and 8 being in line \i*itli...these rollers so that the angle members willpass over them when they leave the rollers. k 1 p a My present invention provides a simple and efl cient' feed mechanism for operating the movable floor or carrier, the partsbeing simple and easily assembled, and irnop'erati on'are not liable to getout of order, andit.

is'particnlarly eliicient when the, vehicle is being operated over hillyground, 'for'While'Q the ratchet and pawl devices, are positively connected with the carrier when the oper-' ating devices are turning in one direction, the

, worm and worm wheel serve practically a lock, and supposing a machine to be ascendinga hill, the tendency of the carrier acted upon by the heavyload of matcrlal resting on it, willtend to move'unduly toward the rear, this will be prevented by the worm and worm Wheel whicn are of such a pitch that the turning force on the worm wheel 18 cannot rotate it, and in this case the carrier will be advanced. only as fast as the ratchet and pawl devices operate. The aroved construction for the floor sections a so provides a simple and efficient connection whereby the sections are hinged together, and the links of the hinges serve as a chain for the 2. in a fertilizer distributer, the combination with a suitable body carrying a movable carrier, of feed mechanism for the carrier em-- bodying an operating shaft, a worm Wheel and worm connection with said shaft, a worm shaft carrying said worm, a pair of oppositelyarranged pinlons having ratchet connections with said worm shaft, a gear cooperating with said pinions for operating them, and operating means for said gear.

3. In a fertilizer distributer, the combination-with a suitable body carrying a movable carrier and an operating-shaft for the carrier, of a feeding mechamsm-fonthe carrier embodying a worm wheel,a clutch interposed between the worm wheel, and the shaft, a worm cooperating with the said worm wheel, a rocker arm, a pair of ratchet and pawl devices interpos'ed between the arm and the worm and adapted alternately to connect the arm with the worm, a slide adjustable longitudinally of said rocker arm, a crank geared to the running wheels of the distributor, and a ,link connecting the crank and the slide.
